I have 1 user account on my domain that cannot login. When the username\password are submitted, the "Welcome" message appears but then it immediately switches to "Logging off" and returns back at the "Press CTL+ALT+DELETE to log on" message. This user account has logged on the domain successfully for the last year.
I have tried to login with this users credentials on different Windows Vista and Windows 7 workstations on the domain with the same result. Any idea where to start troubleshooting this?
